CEMENTING-MACHINE.

Specification of Letters Patent. Patented July 1113, T915.

Application filed March 14, 191.0. Serial No. fi l-9,188.

T 0 all whom it may concern:

Be it known that l, Gannon J. JULIAN, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain limprovements in Cementing-Machines, of

which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for applying adhesive material tostock and is herein set forth as embodied in a machine for applyingcement to the soles of boots and shoes.

It is common in the manufacture of boots and shoes to skive the edges ofthe soles particularly at the shank portion. This results in a sole thethickness of which is not uniform so that when such a sole is runthrough a cementing machine of the ordinary type only the surface of thethicker portion of the sole is properly coated.

Accordingly one feature of this invention consists in the provision in amachine for applying cement to stock of which the surface to be cementedhas relatively 'high and low portions, of means for forcing the high andlow portions of said surface into a common plane whereby all portions ofsaid surface may be evenly coated. Any convenient mean may be made useof, and in the illustrated embodiment there is provided a cementapplying roll and a presenting roll, the latter comprisin independentlyyieldable sections, the springs by which said sections are supportedbeing of sufiicient strength to force the thinner portions of the soletoward the applying roll so that all portions of the face of the sole towhich cement is to be applied lie approximately in the same plane, thusinsuring an even coating of cement irrespective of variations inthickness of the sole. Preferably this roll is bodily movable againstthe force ofa resilient member so as to permit the roll to yield toaccommodate soles of different thickness, the yielding sections takingcare of the unevenness that may exist in any given sole.

It is essential that no considerable amount of cement be permitted toreach the sectional roll since otherwise the sections would soon becomegummed together and the function of said roll thereby impaired.

Accordingly another feature of this invention consists in a constructionof parts whereby cement is prevented from being applied to the sectionalpresenting roll. In the illustrated embodiment a cement applying rolland a stock presenting roll are provided, said presenting rollcomprising yielding sections as indicated above and in order to preventcement from being transferred from the applying to the presenting roll.the applying roll is formed on its periphery with ribs which arepreferably V-shaped, and the cement is supplied to said roll by aconduit having a nozzle, said nozzle comprising a scraper or spreader toconfine the cement on the exposed surface of the roll to the spacesbetween said ribs and a dam yieldable in the direction of rotation ofthe roll to permit any surplus cement to be carried back into theconduit. The ends of the roll are also beveled and cooperate withobliquely arranged scrapers to direct the ce-- ment toward the center ofthe roll.

Another feature of this invention consists in the provision on thecement applying roll of ribs which are obliquely arranged withrespect'to the scraper so that as they come into position beneath saidscraper their longest extent is oblique to the plane of its face.Formerly ribs have been provided which encircled cement rolls but theirdisadvantages have been two-fold: first, so long as the grooves betweenthem were free, the cement has tended to work out through them to theexposed surface of the roll, and second, if any extraneous material waspresent in the cement these grooves became filled with it so thatpresently the scraper held back the cement almost completely, and theexposed surface of the roll ran practically dry. Ex-

. traneous material, such as particles of leather, cloth and certaindirt of an unclassifiable nature is present in all shoe manufacturingestablishments, and a certain amount of this ultimately finds its wayinto the cement. The result,'therefore, has been that these rolls havingcircular ribs at first carried too much cement and finally carried toolittle so that it became necessary to remove them from the machine andclear out the grooves. Under certain circumstances too these circulargrooves may be rendered are automatically ineffective in another manner.The particles of dirt may gather on the scraper and extend down into thegrooves thereby transforming the scraper-into an effective comb whichholds back practically all the cement. With the present construction,however, if particles of dirt get into the grooves they worked out andtransferred to the stock instead of being pushed around and packed intothe grooves. Moreover, the obliquely arranged ribs serve to cut from thebottom of the scraper any particles of dirt which may tend to clinthereto. The result is that the roll carries uniformly the proper amountof cement.

Another feature of this invention consists of a roll comprisingindependently yieldable sections, said roll being particularly adaptedfor use with cementing machines.

These and other features of the invention including certain details ofconstruction and combinations of parts will be described in connectionwith the accompanying drawings and pointed out in-the appended claims.

Referring now to the accompanying drawings, Figure 1 is a perspective ofa machine embodying the invention. Fig. 2 is a cross section on a planepassing between the sections of the respective rolls Fig. 3 is a detailshowing a. skived sole between the rolls, the skived edges of said solebeing bent up into contact with the applying roll, and Fig. 4 is across-section of a skived sole, the dotted lines indicating the positionit assumes when subjected to the action of the rolls as shown in Fig. 3.

Upon a shaft 1 is mounted a cement applying roll. Above said roll is acement supplying reservoir 2 provided with acon-- duit which terminatesin a nozzle in contact with said roll.. This nozzle is shown in sectionin Fig. 2 and comprises a scraper or spreader 3 located with respect tothe direction of rotation of the roll as shown in Fig. 2,, and a dam 4arranged to yield in the direction of rotation of said roll so as topermit any surplus cement to be carried back into the conduit but toprevent said cement from working out of said conduit in the oppositedirection. Attention is particularly directed to this yielding dam sinceotherwise the cement would tend to bank up on the outside of the nozzleat this point during the operation of the machine and to drip down uponthe presenting roll (presently to be described) when the machine was notin use. In order still further to insure that no such dripping may occurwhereby cement might be applied to the presenting roll -a plurality ofV-shaped ribs 5 are formed upon the surface of said roll which,

as will be apparent, tend to hold the cement securely against dripping.v

ments and construction Although in the illustrated embodiment the ribson the cement applying roll are shown as V-shaped, it should be notedthat they are also arranged obliquely with respect to the scraper andthat this oblique arrangement has distinct purposes; first, to cut fromthe operative face of the scraper any extraneous material which maycling to it and second to cause any particles of such matter which maybecome lodged in the grooves to be transferred to the stock. I

As has been stated the ribs in the illustrated embodiment are given aV-shape and in order to facilitate the production of such ribs said rollis made in sections 6 each providedwith oblique ribs and these sectionsare hel together with their ends abutting by bolts which pass throughdisks 8 fast to the shaft 1.

The presenting roll 9 comprises a plurality of sections 10 in the formof rings. Each ring is held in position by a plurality of supportingmembers 11, between which are placed springs 12 each section havingseparate supporting members and springs whereby it is separatelyyieldable. It should be noted that these springs act in opposition toeach other as well as to force the supporting members outwardly so thatsaid members are held spaced from the shaft. A shaft 13 revolublymounted in a swinging bracket 14 carries near its ends disks 15 whichare connected by bolts or rods 16, said rods serving as stops whichcooperate with lugs 17on the supporting members 11 to limit theiroutward movement. The adjustof the presenting roll are such that thesections are revoluble with respect to each other and are independentlyyieldable radially of the shaft. The bracket 14 in which this presentingroll is mounted is pivoted at 18 to the frame and is normally held inraised position by a spring 19 which encircles a rod 20, said rod beingpivoted to the frame at 21 and carrying threaded upon its upper end awingnut 22 by which the motion of the carrier due to the spring may belimited. This spring 19 is provided to normally hold the bracket 14 andwith it the shaft 13 in its uppermost position but to permit saidbracket to yield to accommodate soles of different thickness, thesprings 12 acting to force the thinner portions of the sole into contactwith the cement applying roll as shown in Fig. 3.

The cement reservoir 2 is provided with slides 24 arranged to rest uponguides 25 so that said reservoir may be readilv removable. The scraper 3and the yielding dam 4 are held in place by screws as shown, and theflow of cement is regulated by a valve 26 having in its effectiveportion the form of a mutilated cylinder as shown in Fig. 2. The shaft 1carries fast and loose pulleys 27 meshes and 28. A presenting table 31is adjust ably fastened to the front of the bracket 14: by wing-nuts 30and a similar receiving table 29 is similarly fastened to the rear ofsaid bracket. The base of the machine is adapted to be bolted to a tableor other support as shown in Fig. 1, and an upstanding portion 32carries the bearings for the shaft 1. The edges of the disks 8 arebeveled as shown in Fig. 1 and cooperating with said beveled edges areWipers 33 to direct the ocment toward the center of the roll.

in operation power is applied to the shaft 1 and the v alve 26 opened,the cement then passing into the nozzle. As the cement applying rollrevolves the oblique ribs contact with the scraper 3 whereby the cementis confined to the grooves between said ribs, and inasmuch as said ribsand grooves form Vs as shown, the cement cannot work around theperiphery of the roll and accumulate in any particular locality whichaccumulation might result in dripping of the cement upon the lower roll.Moreover, the oblique ribs serve to cut from the bottom of the scraperany lumps of cement or extraneous material which may cling thereto aswell as to cooperate with the stock to remove from the grooves in saidroll and transfer to said stock any such material which may becomelodged in said grooves. The yielding dam effectually prevents the cementfrom working out beneath it and at the same time permits surplus cement,if any, to pass back into'the conduit.- As the stock (for example askived sole) is fed between the rolls its thickest unyielding portiondetermines the amount of compression of the spring 19 and hence theposition of the shaft 13 while the yielding sections force the thinnerportions of the stock upwardly into contact with the cement applyingroll.

It should benotedthat the machine is particularly adapted for cementingcomparatively thick stock, such as sole leather, which is not of uniformthickness and that means are provided for distorting said stock so thatthe surface of the thinner portions to which it is desired to applycement is forced into contact with the cement applying means.

For convenience the term cement has been used throughout thespecification but it should be understood that the invention may be usedin the application of any liquid or plastic substance having adhesivequalities.

The invention has been set forth in connection with a certain machine,but it should be understood that it is not limited in the scope of itsapplication to the particular machine shown and described.
